C++程序设计中动态内存使用技术探讨

使用new和delete操作符动态分配和回收内存是C 语言的一大特征，它能提高程序的可靠性?本文讨论了C 语言的动态内存使用技术，举例说明了该技术在程序设计中的应用，并对使用中的常见问题给出了简单的解决方法。     

An empirical comparison of seven programming languages

Often heated, debates regarding different programming languages' effectiveness remain inconclusive because of scarce data and a lack of direct comparisons. The author addresses that challenge, comparatively analyzing 80 implementations of the phone-code program in seven different languages (C, C++, Java, Perl, Python, Rexx and Tcl). Further, for each language, the author analyzes several separate implementations by different programmers. The comparison investigates several aspects of each language, including program length, programming effort, runtime efficiency, memory consumption, and reliability. The author uses comparisons to present insight into program language performance     

Cape: extending Clips for the internet

This paper describes Cape, a programming environment combining Clips And Perl with Extensions. Clips is an efficient and expressive forward-chaining rule-based system with a flexible object system. Perl is a popular procedural language with extremely powerful regular expression matching facilities, and a huge library of freely available software. Cape closely integrates these languages, and provides extensions to facilitate building systems with an intimate mixture of the two. The paper describes the facilities Cape offers programmers and the demonstration systems and “component applications” distributed with it. The use of the system is then discussed with reference to dime (Distributed Information Manipulation Environment), a toolkit being developed to support identifying and coordinating the use of external knowledge sources. Finally, planned developments of the system are indicated.     

See What You Need: Helping End-users to Build Abstractions

It has been argued that most end-users would not want to write programs, no matter what kind of tools they had to help them. This paper analyzes the reasons for that situation, and addresses them with a new approach to programming. There is a large class of users who are very reluctant to create any kind of abstraction within a computer (they will not create a new directory, let alone a Word macro). But these people do create abstractions in their everyday lives outside the computer. The reason for their computer habits can be explained in terms of a simple investment and risk model. See What You Need (SWYN) is a system intended to deliver the capabilities—not just of Word macros, but of Perl—to end-users. The techniques it adopts are those of programming by example, visual program representation and direct manipulation. SWYN is not intended to be a complete system, and is unlikely to develop into a complete Perl replacement. It is a research vehicle, supporting the evaluation of specific features aimed at reducing the perceived risk of abstraction in programming. This paper describes two elements of the SWYN project, both of them related to the regular expressions that are central to pattern matching in Perl. The first is a prototype system that acquires regular expressions from the type of examples required in direct manipulation of data for programming. The second is an experimental evaluation of alternative notations for visualizing regular expressions. This experiment demonstrated a clear advantage for graphical notations in typical end-user tasks, both over conventional regular expressions, and over a tutorial-style textual notation. The overall effect is a reduction both in programming investment and in perceived risk.     

GNU Emacs as a dynamically extensible programming environment

GNU Emacs is usually used only as an extensible editor. However, the ability to integrate inferior processes into GNU Emacs makes it an attractive programming environment. Like Interlisp and Smalltalk-80, GNU Emacs can be extended dynamically by its user. Unlike these programming environments, it can be used easily as a programming environment for an arbitrary programming language, and not just for its extension language. This paper discusses the methods of extending GNU Emacs and how we have applied them in creating a programming environment for a high-level specification language called AGENT.     

Interactive programs in a functional language: A functional implementation of an editor

The transition from imperative programming to functional programming for problems whose mathematical nature is not immediately obvious raises two questions. First, how can the function concept be applied to such problems, and, secondly, what language concepts are most suited in this situation. This paper shows that an existing functional programming language is very well suited for the elegant implementation of interactive programs. As an example, a text editor is described. The implementation of the editor has once more demonstrated the benefits of functional programming: fast generation of short and reliable programs. This indicates that it is worth while to investigate the application fields of functional programming languages as well as their implementation, in order to try to make them into general-purpose programming languages that can be used in a production environment.     

A graphical user‐interface and an image processing toolkit for Perl

Perl is a powerful language for writing portable programs on a wide range of platforms. In this article two stand‐alone Perl toolkits, Prima and IPA, are presented, which provide graphical user interface and image processing functionality with features not found in any other Perl toolkits. Prima is a platform‐independent Perl graphic toolkit with an object‐oriented interface. Its features include an extensive set of Perl‐coded interface elements, a wide range of image types and conversion routines, and a visual builder. IPA is an image processing toolkit based on Prima functionality, and it provides a set of common two‐dimensional operators. Prima and IPA are used as a base for biological research, where the effects of various peptide‐based preparations on neuron culture are studied. Copyright © 2005 John Wiley & Sons, Ltd.
